Eat at least five servings of fruit a day. If you're not getting an apple a day -- or any fruit for that matter -- it's time to change your unhealthy ways. A campaign has been established promoting the importance of consuming five to nine servings of colorful fruits and vegetables every day. Fruits and vegetables provide vitamins, minerals, fibers and other health-enhancing properties. They're also responsible for warding off cancer and other deadly diseases. Antioxidants like lycopene -- found in tomatoes and tomato products like ketchup - plus phytochemicals help neutralize free radicals, which play a part in the development of certain cancers. Other healthy dietary habits can ward off cancer as well. The fiber in fruits and vegetables, especially those whose skin can be eaten like potatoes and apples, help food move through the intestines and out of the body, promoting a healthy digestive system and colon.
